1.3 Version is working well but I was thinking of a scenario that could be a problem, the LED right now ignores the schedule.

So once I fix that then it's good to go. I have noticed that on some devices an incoming call is for some reason similar to touching the keyboard or trackwheel. So what you are seeing is the email/sms alerts being cleared by the incoming call and then when you miss the call then it starts on the missed call alert.

There are options in 1.3 to not log alerts and if you turn off the option to pop up on notification then the screen will stay in the background.
